Question:medium

If the price of petrol increases by 25% and Raj intends to spend only an additional 15% on petrol, by how much % will he reduce the quantity of petrol purchased?

Show Hint

You can use the formula: \( \text{New Quantity} = \frac{100 + \text{% change in Expenditure}}{100 + \text{% change in Price}} \times \text{Old Quantity} \). Here, \( \frac{115}{125} \times 100 = 92 \), so the reduction is \( 100 - 92 = 8% \).
